Notes:

1. THZ and TOHZ are defined as the time at which the outputs achieve the open circuit condition

and are referenced to the VOH or VOL.

2. At any given temperature and voltage condition THZ(max) is less than TLZ(min) both for a given

device and from device to device.

3. WE# is high for Read cycle.
